I've always been a rather "frisky" girl, but going Primal seems to have given me more energy when "frisky" and greater ability to relax when not.
Want sex pretty much every day, either in the morning or at night, if not both.
All other signs of high-testosterone are there too, mind: increase in muscle volume, more body-hair, more regular cycle, more comfortable cycle, less stress and less emotional ups and downs.
I'd say it's the fat that does it.
I rarely talk to people about Paleo/Primal, but, when I do, it's when they're NOT complaining about their weight or health.
You see, I don't really "do" pity. And one thing I've learned about people is that they're more open to suggestion when they're happy and stable. When they complain they only ever want pity, not to be advised.
